Hi SAS Users,

I need to test bioequivalent between two treatment. Bioequivalence is defined as 90% CI of the geometric mean ratio between treatment and reference lines within 0.8 and 1.25. 

 

I have a sample data set that is from a guideline and I want to write the code which can generate the same outputs as the guideline. 

 

I used the ID,  seq, period, AUCt data in Table A1-E and A1-F from the linked PDF. It should come up with the output on Table A1-H and A1-I.

I also attached the sas data set here. 

 

I have tried several sets of code and cannot find the same outcome. Particularly the output on Table A1-I (parameter as subject(seq) and residual with their variance. How should I modify the code?

 

/* using proc mixed*/

PROC MIXED DATA = MBHC.SAMPLE;
CLASS ID SEQ PERIOD FORMULATION;
MODEL LNAUC =SEQ PERIOD FORMULATION/ DDFM = SATTERTH ;
RANDOM FORMULATION/TYPE = FA0(2) SUB = ID;
REPEATED/GRP = FORMULATION SUB = ID;
ESTIMATE "T VS. R" FORMULATION 1 -1/CL ALPHA = 0.1;
RUN;


/* using GLM*/

PROC GLM DATA=MBHC.SAMPLE ;

   CLASS ID SEQ PERIOD FORMULATION  ;
   MODEL LNAUC =SEQ PERIOD FORMULATION;

RUN ;

 

Output I want:

 Thank you.

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
